• A high operational availability is achieved through optimizing the internal factors of production organization, minimizing the needed set-up and unproductive times (e.g. for relocation or blasting), as well as constructive factors like for example long maintenance intervals with short maintenance times. Furthermore external cost –determining factors like e.g. short-term availability of spare parts and mechanics, as well as the possible need for special tools (e.g. hydraulic presses, motor testers, etc.) are considered in the calls for bids. • Optimum consumption data of the machines, the secured possibility of using low-cost raw material, additives and lubricants, as well as energy carriers, the usage of standardized and universally available spare and wear parts are considered as main aspects for an economical operation. • User-friendly diagnosis and control systems, as well as an appropriate automation serve as data basis and instruments for exact control, invoicing and target/ performance comparison. • The intersections between partial systems are designed in a way that the different operating characteristics (e.g. continuous and discontinuous), capacities, as well as amounts or sizes of material streams do not lead to disturbances in parts or in the entire system. Appropriately dimensioned buffer units were applied for decoupling in case of very different characteristics. Planning Data and Steps The conducted market analyses and evaluations of economic efficiency were discussed intensely with investors and translated into a corporate investment concept. The aspired market volume is 1.500.000 t/year in the target regions Ukraine, East Poland, West Russia. The planned amount is to be produced in two shifts, so that timely adjustments can be made to react to additional or lower demand. Considering the local climate data, it is expected that without weekend works, there are 200 assured production days. The basic technical parameters are summarized in the following picture. The implementation of the observations with regard to planning, which have been discussed for far, as well as the outlined criteria with regard to the need of investigations and requirement criteria calls for a multitude of steps. The basic tasks and steps are made clear in picture 3. Issue 04 | 2010 TRANSFER OF TECHNOLOGY Selected Aspects of the Conducted Open Cast Mine Planning In the following chapter, selected aspects of the open cast mine planning, which have formed the basis of the required specific call for bids for the purchase of equipment, services and plants, are discussed. Selection of Mine Development and the Initial Mine The deliberations on planning, which are partly presented here, are based on the location, as well as the geometry of the licensed authorized field. Picture 4 shows the boundary lines, position of the exploratory drillings, as well as the distribution of the iso-lines of overburden. The top ground surface lies at a level between 170 m and 182 sea level. The maximum mining depth is currently limited by approvals to the level > 86 m above sea level. Therefore under an overburden thickness of 3 to 12 m, there is a minimum of 84 m of mineable rocks. According to Ukranian regulations, the maximum bench distance cannot exceed 14 m. Active Benches have to be planned at 75° to 80° and end-benches at 55°. Taking into consideration these basic parameters an exploitation over several benches is planned, where 6 benches are for exploitation of raw material and one bench is for overburden. The location of the processing plant, as well as the required stocks is placed at the south-western border, outside the authorized field, since it has the shortest distance to the road, 200m. Furthermore the authorized field tapers out in the western part, with overburden thickness of more than 9 m. The initial mine is located in the area of drilling 2, with a low overburden. In order to quickly produce quality muck, the initial mine is planned with two benches, with a bench high of 14 m each. While the first bench might still have weathered material, high quality material can be expected in the 2nd bench. The first phase of the mining development to approximately 3 ha is implemented with sub-contractors with mobile processing plants, as well as with dumper operation. The incoming waste material is mainly used as filling material and the rocks of the first bench are processed and marketed as aggregates. www.advanced-mining.com 18
